There were recent medical tests and investigations carried out in both the US and UK which showed that there was evidence showing the covid virus was still present in aerosol droplets much smaller than was first thought possible. The scientists conducting the test were yet to determine whether or not the virus was still in its contagious form whilst in these micro-droplets or whether they were "dead/harmless" but there existence has been reported. These aerosol droplets remain in the air for up to two hours after being exhaled which is much, much longer than was first thought and COULD be evidence that covid19 is in fact airborne.
I might do a search and post the relevant press releases to show you the evidence, but I probably won't as, tbh, I can't really be arsed. But there is evidence out there which suggests that you are/may be incorrect.
Maybe you could do the search yourself and save me the time and effort?
